4x4mm power inductors take up to 28.5A

The XEL40xx Series of low-loss power inductors released by Coilcraft comes with lower inductance values that have been fully optimized for high frequency applications.

They also offer extremely low DCR (as low as 2.5 mOhms) and ultra-low AC losses, resulting in the highest efficiency across a range of frequencies (2 to over 5MHz). They are offered with current ratings as high as 28.5 Amps, and their soft saturation characteristics can withstand high current spikes.

The XEL40xx Series inductors measure just 4x4mm with maximum heights as low as 1.2 mm, making them suitable for IoT and portable device applications. They feature RoHS compliant tin-silver over copper terminations and are halogen free. The XEL4014 and XEL4020 models are qualified to AEC-Q200 Grade 1 standards (-40° to +125°C ambient) for specification into harsh-environment applications.
